POMONA >> Residents along San Bernardino Avenue heard a man screaming for help after shots rang out late Tuesday.

A woman, who identified herself as Tiffany Jones, ran outside and saw the man collapse in her yard.

“When I came out, a dude was shooting at him, so I ran back inside,” she said.

Another man lay wounded across San Bernardino Avenue near Wayne Street. He survived the attack, but Patrick Cooper, the man lying in Jones’ yard, died at the scene.

It was one of two deadly shootings that occurred within two hours and two miles of each other in Pomona. Police are unsure if the incidents are connected.

“If they were 20 minutes apart or 30 minutes, that would suggest a good possibility that they’re related, but being two hours apart, it’s hard to tell,” said Pomona police Lt. Eddie Vazquez.

Police received a call at 11:55 p.m. regarding the incident on San Bernardino Avenue.

Paramedics took the surviving victim to an area hospital where he was listed in critical condition.

Lacresia Dennis, Cooper’s mother-in-law, came to the scene early Wednesday to find out what happened. Soap and blood remained on the sidewalk, along with a paper bag containing rubber gloves and other items left behind by either emergency or forensic personnel.

Dennis said Cooper had drug problems but said police told her the incident appeared to be random. She described him as a good father, who was raising two children with his wife.

Dennis wasn’t sure what Cooper’s relationship was with the other victim, who remains unidentified.

At 2:03 a.m., police received a report of a man lying on the ground about two miles from the first incident. Officers found that victim at the corner of Holt Avenue and Paloma Drive.

“An officer checked on him and saw he was suffering from a gunshot wound,” Vazquez said.

Paramedics took him to a hospital where he succumbed to wounds from the shooting. Police identified him as 25-year-old Pomona resident Covan Brady. All that remained from that crime scene was a single medical glove lying in the middle of Paloma Drive between a doughnut shop and a restaurant.

As of late Wednesday afternoon, police had not made any arrests or determined motives in either incident.

Pomona has had 24 homicides this year, compared to 17 for all of 2012.
